Adds a parameter specification for a parameter encountered within this node. We use the term 'embedded' here because of the fact that the parameter was simply encountered as part of the node's text; it does not exist as part of a subtree as it might in a true AST.

Retrieve all embedded parameter specifications.

Determine whether this node contans embedded parameters. The implication is that {@link #getEmbeddedParameters()} is allowed to return null if this method returns false.

Set the renderable text of this node.
